Write a C# Sharp program to create a string using three copies of the last two characters of a given string of length at least two.

Visual Presentation:

Sample Solution:-

C# Sharp Code:

using System; // Import the System namespace which contains fundamental types and base classes

namespace exercises // Define a namespace called 'exercises'
{
    class Program // Define a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {
            // Output the result of the test function with different strings as arguments
            Console.WriteLine(test("Hello")); // Test with the string "Hello"
            Console.WriteLine(test("Hi")); // Test with the string "Hi"
            Console.ReadLine(); // Wait for user input before closing the console window
        }

        // Function definition of test function that takes a string 's1' and returns a string
        public static string test(string s1)
        {
            // Get the last two characters of 's1' and store them in the 'last2' variable
            string last2 = s1.Substring(s1.Length - 2);

            // Concatenate 'last2' with itself three times and return the resulting string
            return last2 + last2 + last2;
        }
    }
}

Previous: Write a C# Sharp program to insert a given string into middle of the another given string of length 4.
Next: Write a C# Sharp program to create a new string using first two characters of a given string. If the string length is less than 2 then return the original string.
